  • the locking device 30 is alternatively designed such that the second spring 17 'not as in the first embodiment between a downwardly open circular groove 33 of the rotary cam 5 and formed on the base element 15 to the end of the detent pin 9 formed spring seat is arranged.
  • the second spring element 17 'between a recess of the push button 7 and projections 10 of the locking pin 9 is arranged in the axial direction.
  • the rotary cam 5 can move relative to the locking pin 9 in the axial direction.
  • the push button 7 is always pressed up regardless of the position in which the locking pin 9 is located. Ie.
  • FIG. 13 shows an exploded view of another variant of the storage device according to the invention (similar to the illustration in FIG. 3 ), which differ from the one in FIG. 3 shown embodiment differs in that here in a bearing element 24 'in the base unit 15 from above, ie first a dome on the axis of rotation D of the carrier 2 penetrating, a screw 25 is screwed, which serves as a rotation axis for the carrier 2.
  • the bearing element 24 ' may, for example, also be designed as a dome with an internal thread, into which the screw 25 is screwed with a washer 26.
  • the carrier 2 is locked by the screw 25 in the axial direction, but can rotate about the screw 26 as a rotation axis D.
  • 15 additional optional sliding segments 27 are arranged between the carrier 2 and the base unit, the ensure a particularly low-friction rotation of the carrier 2 relative to the base unit 15.
  • FIG. 3 are also in FIG. 13 in addition to the reference numerals Roman numerals I. to VI. inserted, which indicate the order of the assembly steps. It can be seen that in this embodiment, in which the rotatable anchoring of the carrier 2 takes place on the base unit 15 by means of the screw 25 from above, at the very end the tray 21 is inserted in the carrier 2 and clamped for example by means of detent.
  • the other components for example, analogous to the arrangement in the FIGS. 1 to 10 be educated.
